【 摘 要 】

tsTheoretical calculations reveal that Nicandra physaloides pectin can serve as Lewis base to realize strong interaction toward both lithium polysulfide and polyselenides.Nicandra physaloides pectin is introduced into a conductive double-carbon self-supporting film to build an anchoring and regulating interlayer for Li–SeS2 batteries.The Li–SeS2 pouch cells assembled with the interlayers deliver good flexibility and stability to demonstrate a viable strategy for developing working Li–SeS2 batteries.
